FIGS. 10-18 diagrammatically illustrate a method for installing baseballpitching mound form 10 for constructing a baseball pitching mound andsecuring a pitcher's rubber in a synthetic turf of a baseball diamondfor playing the game of baseball, according to an embodiment of thepresent disclosure.

Initially, as shown in FIGS. 10 and 11, profile guide members 20 arebolted to prefabricated center frame section 100 at corresponding holelocations using connection hardware such as bolts and nuts.

With reference to FIG. 12, project specific drawings may be checked todetermine the field location for the assembled center frame section 100and profile guide members 20 on a support structure 12 such as theground or a layer of stone. As shown in FIG. 12, the location of centerframe section 100 is set such that the inner front edge 188 of pitcher'srubber frame 180 for receiving the pitching rubber will fall 60 feet and6 inches from the apex of a home plate (not shown) in the direction ofarrow A, along with ensuring that the major sides of center framesection 100 are parallel to the sides of the home plate. In someembodiments, the ground 12 may be prepped and leveled to provide a levelsurface on which the assembled center frame section 100 and profileguide members 20 are placed. The appropriate installation elevation maybe achieved by excavating or site preparation in a suitable manner.

As shown in FIG. 13, four prefabricated peripheral frame sections 200,300, 400, and 500 are aligned with center frame section 100, andoperably bolted together at the various alignable hole locations usingconnection hardware as shown in FIG. 14. The assembled pitching moundform, as shown in FIG. 14, is staked in place by driving ½ inch rebarthrough provided holes in the plurality of the horizontal cross-membersof the peripheral frame sections, for example, regarding outer framesection 200 installed through holes 272 in the web of cross-member 270and installed through holes 282 in the web of cross-member 280. Therebar may have an upper end having an enlarged head, L-shape, or curvedhook shape. The rebar stakes may be about 1 foot to about 2 feet long.In some embodiments, horizontal rebar may be positioned across and laidon top of or in notches in the cross-members. In other embodiments, amesh may be disposed on top of the cross-members. As shown in FIG. 15,the remaining profile guide members 22 and 24 are operably installed,for example, bolted at one end to center frame section 100 and bolted atthe other end to a corresponding cross-member adjacent to the arcuatesides. The distal ends of profile guides 20 may be operably attached theperipheral frame sections adjacent to the arcuate side.

As shown in FIG. 16, uncured concrete 600 is poured into or placed inthe center frame section 100 and peripheral frame sections 200, 300,400, and 500 of the assembled baseball pitching mound form 10. The upperedges 212, 312, 412, and 512 of arcuate members 200, 300, 400, and 500,the upper surfaces of profile guide members 20, 22, and 24, and theupper surfaces of the side members and cross-members of center frame 100allow for installation personnel to screed or pass a leveling deviceover the uncured concrete to provide a level and/or even uncuredconcrete surface that tapers from the center frame outwardly towardsupper edges 212, 312, 412, and 512 of arcuate members 200, 300, 400, and500, respectively. The concrete is allowed to cure and harden so thatthe center frame section and the peripheral frame sections are anchoredto the ground. It will be appreciated that the assembled baseballpitching mound form is configured to have sufficient strength tomaintain it shape when filled with the uncured concrete.

The space around the outside of the arcuate sides 210, 310, 410, and 510of the peripheral frame sections may be back filled with stone 13 to thetop of the arcuate sides. In some embodiments, the backfilling withstone around the perimeter of the assembled baseball pitching mound formmay be performed before the concrete is poured and cured.

With reference to FIG. 17, once the concrete 600 has been placed andcured, a synthetic turf 650, a portion of which is shown in FIG. 17, canbe cut and secured over the baseball pitching mound form 10 with thecured concrete 600.

As shown in FIG. 18, synthetic turf 650 may be disposed over and securedto the upper surfaces of flanges 185 and 187 of pitcher's rubber frame180, and/or tucked into the pitching rubber cavity such as disposed overand secured to the inner surface of legs 182 and 183. For example,synthetic turf 650 may be secured to the inside vertical side ofpitcher's rubber frame 180 with self-tapping screws. In someembodiments, depending on the thickness of the synthetic turf or thedensity of the fibers or “thatch layer,” the synthetic turf fibers ofthe synthetic turf may be shaved down as necessary during this step toallow for clearance for receiving a pitcher's rubber 11. By securing thesynthetic turf inside the inner frame, a friction fit may be achievedwith pitcher's rubber 11. The pitcher's rubber may be a standardpitcher's rubber. For example, the pitcher's rubber may be a replaceableSHBBPB Schutt Four-Sided Professional Pitching Rubber. With referencestill to FIG. 18, a pitcher's rubber height can be adjusted as needed byadjusting the height of adjustable supports 189, for example, adjustingthreaded members or bolts. For example, the adjustable supports may be ⅜inch treaded studs and bolts.

In other embodiments, the synthetic turf may include a horizontal lipthat borders the cavity for the pitcher's rubber, such that thesynthetic turf will be fastened to the upper flanges surrounding thecavity using an adhesive and/or fasteners such as self-tapping screws.

With reference to FIG. 19, in some embodiments, a synthetic turf 670 mayinclude a stand-alone replaceable rectangular synthetic turf portion675. The attachment of the replaceable rectangular portion 675 may besecured adjacent to the pitcher's rubber as described above. Sincereplaceable rectangular portion 675 is in a high wear area, thereplaceable rectangular portion 675 can be replaced without the need toreplace the remainder of the synthetic turf 670 that is disposed overthe pitching mound. In other embodiments, a rubble layer 660 may bedisposed between the cured concrete and the synthetic turf 650 of theinstalled pitching mound form, or under the replaceable rectangularsynthetic turf portion 675. The rubber layer may extend over the entireouter frame section.

For example, center frame section 100 may have a length of about 106inches and a width of about 60 inches. The outside diameter of thepitcher's mound form 10 may be about 18 feet.

With reference to FIG. 20, therein illustrated is a baseball bullpenpitching mound form 1000 for use on synthetic turf (not shown in FIG.20) for providing an elevated pitching mound and support for a pitcher'srubber 1011 for a pitcher to practice pitching in a bullpen, accordingto an embodiment of the present disclosure. For example, baseballbullpen pitching mound form 1000 may generally include a plurality ofprefabricated frame sections 1012. Each of the plurality ofprefabricated frame sections may define a hollow frame section having anopen upper surface and an open bottom surface. As described in greaterdetail below, the assembled baseball bullpen pitching mound form may befilled with concrete.
